Hi Paul

I suggest you read this 7687 programming with CS3.pdf (412kb) downloaded 219 time(s).
From page 1 it shows how to program the 7987 with a CS3 with a s/w version 1.3.1 or later (now is 2.2.0 (5)
If not modified, the base address is 225 (old Keyboard 15) and when the soldered bridge is made, the address is 209 (old Keyboard 14)
Programming
1 - You have to first select your Track 1 and position your TT accordingly
2 - push the clear button to start clean
3 - Use the "Step" button to reach the next track used, then push the "Input" button
4 - Repeat 3 until all used tracks have been entered
5- Finish the programming session by pushing "End"

Use
* By dragging the deck on the Touch display
* By selecting the track by its position number on the display
* By using the two "Step" buttons.
* By pushing "Turning the Deck" to turn the turntable deck 180 degrees.

it seems that the direction of rotation is the last one used (it seems there is not calculator to check the shortest way as with a DSD2010 and Rocrail in my case.
I hope this helps
Just for fun, here is my TT 7286 with its decoder DSD2010 a CS2 (at the time) and Rocrail in full automatic operation

Thank you both.

Unfortunately mine is not behaving. I can use the step buttons (left and right) no problem, but selecting the arrow and then a track number rotates the turntable always in the wrong direction or the wrong track, sometimes not stopping.

I've tried clearing and re-programming without success.

I wonder if there are any other configurations that are different in mine? The address or time (ms) values perhaps?

Some small progress, I can get the track position working, but it is confused with track number. I have tracks at odd numbers (1, 3, 5) but no matter how I set up the track diagram or program the tracks, it moves in single increments.

I've spent hours on this, and have plenty of patience, but this really is not Marklin's finest moment.

When I programmed my 7687 I had to press ”step” or something right before ”end”. If I pressed “end” directly after the last track it didn't work.

Thanks for the tips and information. I've solved the problem through software. By deactivating programming of the turntable in the CS3, the software (iTrain in this case) operates the turntable completely automatically and perfectly. I had incorrectly assumed that the turntable needed to be programmed in the CS3 in order for it to be controllable by software. As it turns out this is not the case, and in fact it works better not programmed in the CS3 (at least with iTrain).

The Märklin 7687 is the biggest piece of garbage I have come across. I just got my CS3 two weeks ago and I have been trying to program the 7687 in that time. I think I have tried 10-12 times to get it programmed according the available instructions out there. No matter how many times I clear the programming and then set the track connections, the turntable bridge decides on it's own which track connection to travel to... I may end up ditching the 7687 and going with another decoder. Anyone have any experience with the LDT TT-DEC?

Thanks. I tried that and it didn't work. I even made sure the TT bridge made a complete 360 before pressing end and it still didn't work.
